In discrete event steady-state simulation, deletion of data from the initial transient phase of the simulation is usually recommended in order to reduce the bias of the final estimates. Various heuristics and tests have been proposed to aid with this. The plummeting cost of simulation, combined with uncertainties about the overall reliability of the estimation of the transient period, suggest revisiting the notion that deletion is essential, especially for longer simulations. We consider this in a sequential simulation framework.
